.To all whom it 77mg concern:

10 ject of the improvements being to simplify the construction and manipulation of the reader and to render its construction less costly.

In order to enable my invention to be fully understood, I will proceed to describe the same by reference to the accompanying drawings, inwhich Figure l represents a plan of a self-acting reader for the Jacquard constructed according to my improvements, the pointers or indices being removed for the sake of clearness. Fig.

2 is an end view of the same, and Figs. 3 and 4 are sections on the lines A B and O D, respeetively, of Fig. 1. Fi 5 is a detached sectional View of the arrangement I employ for setting the punching-levers. Figs. 6 and 7 full-sized elevation and section, showing an arrangement of pointers or indices which I can employ with my improved reader.

Similar letters in all the figures represent similar parts.

111 carrying out my invention I employ a suitable frame, a, on each side of which a bracket is provided, such brackets being marked 1) and 0, respectively. On the brackct b is a slotted frame, (I, fastened to it at right angles. In the slotted frame (Z is placed a screw, 0, having a fine thread. Thisscrew c' is provided with a handle, f, in front, and a washer and nut at the back end, and passes through a tapped nut, g, the end of which forms an adjustable fulcrum for a slotted lever, h, through which it passes. The lever It carries a stud, t, at one end. This stud takes into the helical groove of a canrwheehj, of

special construction, hereinafter described,

fixed'at the right-hand end of a main crossshaft, 7c. The other end of the lever h has a slot, 13, to receive the rod Z, which depends from the horizontal bar at, carrying the pointers a, hereinafter described. The helical camwhcel j is provided with a sliding piece, 0, which, when the punching of one card has been completed, allows of the return of the pointers a and slotted lever 72. to the position which they occupy when commencing to punch a card, and prevents any possibility of the pin i binding at this point in its course, ashas hitherto been the case when a solid cam has been employed.

p and p are pins on either side of the helical cam-wheel j, for shifting the sliding piece 0 at the required moments as the cam-wheel rotates. In the bracket 0, and on the left hand end of the main shaft 70, I mount a grooved wheel, 9', provided with a projection, r, capable of adjustment radially by means of a nut, s, and screw- 15. This projection 0- actuates a short bent lever, a,on a rocking shaft, 1), at each revolution of the main shaft 70, and thereby operates the pawls w by means of the connecting-rodsm and 1, and thus moves the toothed wheels 2 z z and front rollers, A A,forward to the required extent, which extent is regulated by adjusting the projection r by means of the hereinbefore-described nut sand screw it. By this arrangement I 'dispense with the slotted lever and cam-wheel hitherto employed for this purpose in self-acting readers, and thus considerably simplify the construction of the machine at this part and diminish the cost of its manufacture.

Ata suitable point on the main shaft 7: is keyed a ratchet-wheel, a. On the boss of this wheel is a triangular-shaped plate, I), to which is fixed a pin or stud, c, and on which is pivoted a weighted pawl, d. This pawl takes into the teeth of the ratchet-wheel a. At the back of the ratchet-wheel a, and working on a pin, 0, screwed into a projection cast on the frame a is a spring-eatcl1,-f, formed with a tooth or projection, g, which also takes into the teeth of the ratchet-wheel a. This catch f is of a semicircular form, following part of the circumference of the ratchet-wheel a. The pin 0 serves to raise the tooth or projection d free of the teeth of the ratchet-wheel a when the ratchet-wheel is to be moved for ward by the pawl d. I

To the lower angle of the plate I) is jointed a connecting-rod, 71.. .Thelower end of this conneeting-rod is jointed to an oscillating lever, i, which has its bearing or fulcrum on a small shaft, j, fixed to the two side frames, a, and just behind and below the card-frame 7c. The other end of the oscillating lever t" is jointed to a rod, Z, the lower end of which is jointed to the treadle m,which wbrks on the shaft a? The back end of the treadle is continued beyond the shaft a, and to the end at each side are jointed connectingrods o and 12 which are jointed at their upper ends to two levers, q, pivoting at 1' on the brackets s, and provided at their free ends with a bar, If, the ends of which work in the guide-plates a and receive the lower ends of rods or bolts i tfiwhich operate the punches. The connecting-rods and 1) have each a strong spiral spring, o o,

fastened to them, and serving to raise the pressure of the foot. The lower ends of these springs are fastened to each side of the treadle m a treadle when it is released from the short distance from the front of the machine.

Below the main shaft k is a bar, w, fixed to each side of the frame a, and near the center of this bar is bolted a slotted bracket, 00, in which works a vertical screw, 3 having afine thread. This screw carries a pin, a, at its upper end, which pin forms the fulcrum of a slotted vertical lever b the said fulcrum being capable of adjustment vertically by turning the vertical screw 9/ either to the right or to the left, as required. This arrangement allows of the fulcrum of the lever 22* being adjusted to regulate the extent of travel of the card-frame it. Through the top end of the lever 12 is fixed a pin, 0 one end of which works in a slotted plate, (i having its lower end bolted or cast on the bracket 00', and the other end having a loose bearing on the main cross-shaft 7s. The other end of the pin 0 works in the groove 6 of a canrwhcel, f keyed on the main shaft Z". The lower end of the lever 12 is jointed to a rod, g", which is jointed to a rod, h", working in a bearing, 2", bolted to the horizontal cross bar 10. This rod is provided with a spiral spring, j one end of which bears on the bearing 1?, and the other end on a collar, 0, formed on the rod h". This spring is for assisting to carry the cardframe It back to its starting-point as each card is punched,the front end of the rod being fastened to the card-frame k is the perforated die-plate bolted to the front of the frame a. Immediately above is what is called the stock-plate Z with corresponding perforations, and holding the row of punches 0. Above the stock-plate Z is the punching-plate m below which is a row of sliding rods or bars, if, having parts of their surfaces cut away on their under side at E and E, these levers corresponding in number with the punches 0 q are cords or chains fastened to the bars a, and passing round pulleys r at the rear end of the same, and connected with the indices or pointers a. The said cords or chains, as shown in Fig. 5, pass over the pulleys f in the pointers a, and are attached to a springrod, sliding within the pointcrvn. The cords or chains (f serve to draw backward the punching-bars a for the purpose hereinafter described, the spring carrying the rod back so as to slacken the cords or chains (1 when it is released.

8 are springs which cause the punchingplate m" and punches o to return to their normal position after each motion of the treadle. The bolts t t are fixed to the punching-plate m, and pass through the die-plate k", the lower ends being jointed to the rod or bar t on the levers q, as hereinbefore described. On the shaft j works an oscillating double crank a if. The top crank, if, fits accurately along the whole line of mnching-bars a and serves to return them to their normal position after each. punching operation, in the following manner: The lower crank, 12*, is forced backward at the return of the treadle by a triangular-shaped frame, a, bolted at its base to each side of the treadle, which frame presses against a springtougue, w, fitted on the crank o, and forces the crank a against the punching-bars of. The spring-tongue of works on a joint at F, which allows the tongue to give way and the frame 00 to pass it when the treadle is depressed, but to remain rigid when the frame no meets it on the upward movement of the treadle.

I can effect the regulation and adjustment of the pointers n laterally in the following maner, reference being had to Figs. 6 and 7 I form each of the pointers hollow and with a slot, 1 on each side throughout nearly its entire length. The center pointer is fixed to the index-frame. Vithin the other pointers slide two short rods, (6*, toeach of which is jointed a rod, If, the other end of the rods 1)" being jointed at c to the end of the next pointer. The center pointer receives the ends of the rods 2)" of the pointers on both sides, as shown. The sliding rods a are each provided with a hole, (1, through which holes are passed rods a, capable of being moved toward or away from each other by any suitable means, such as by right and left handed screws at their ends.

The operation of the improved self-acting reader is as follows: The pattern or design to be read off having been placed on the rollers A A A in the usual manner, the projection r on the grooved wheel 1- is adjustable by means of the nut s and screw 1?, so as to regulate the travel of the pattern on the rollers, according to the scale of the divisions of the pattern-paper. The pointers a are then adjusted laterally to the scale of the divisions of the pattern by means of the right and left handed screws at the ends of the rods 0, which will be caused to approach or move away from each other, according to the direction in which the screws are turned. The rods a,slidingin IOO original position.

the pointers n,will thus, by means of the rods the pointers corresponding with the particular b draw the pointers toward or away from each color to be next read in ,are then pulled,and the other, and the pointers,when thus set,will re main rigidly in position and equidistant from each other. The card to be punched isthen placed, as usual, on the card-plate 7c. The cords q,attached to the pointers, (which indicate the particular color being read in,) are slightly pulled by the operator, and will thereby draw back their corresponding bars, n",into position for punching the holes in the card, and the treadle being new depressed, the bar t will be lowered by means of the levers 0, p and q, and will draw down the rods or bolts 2?, and with them the punching-plate m", which, pressing on the bars a, will cause such ,of the said levers as have been drawn backward by the cords as hereinbefore described, to force their respective punches 0 through the card. The remaining punches will enter the eutaway parts E of the bars of, and will therefore not be subjected to the pressure of the bars a". The cut-away parts Elimit the movement of the bars a By thehereinbefore-described arrangement of cords andvpulleys connecting the pointers with the punching-levers, I avoid the necessity of the operator having to turn his eyes from the pointers to the corresponding keys, which has hitherto been the cause of frequent mistakes, and consequent waste of the cards thus spoilcd,and loss of time. The treadle in being depressed will, by means of the rods Z and h and levert, have raised the plate I), and with it the weighted pawl d, which will thereby have been raised out of the teeth of the ratehetwheel a. The plate b in rising will raise the tooth or projection 9 also out of the teeth of the ratchet-wheel a by the pin 0, which passes under and raises the springcateh f, carrying the tooth g. The treadle, being now released from the pressure of the foot, will draw down the pawl d, and thus rotate the ratehet-wheel a to the extent of one tooth. The main shaft It, being thus rotated to a corresponding extent, will partially rotate the helical eam-wheelj, the groove of which will operate the slotted lever h and the horizontal bar m, carrying the pointers n, so as to move the pointers one single square of the pattern from right to left, as hitherto. The main shaft 75 in rotating also carries with it the earn-wheel f", which, by means of the pin 0 working in the groove of the same and in the slot in the plate d, operates the lever b so as to cause its tail end, by means of the rods g and h, to draw the card-frame backward to the required extent after the row of perforations has been punched in the card. When the treadle is released, the punchingplate W and punches 0 are raised to their normal position by the springs 8 and the treadle in rising carries the frame :r against the spring-tongue w on the double crank a o andpresses the levers a back to their The cords q", attached to treadle is again depressed, and so on, as hereinbefore described, until the perforation of the card is completed. Vhen the perforation of one card has been completed and one line of the pattern read off, the pointers a are brought back to their starting position by the sliding piece 0 in the helical cam-wheel j (into one end of the groove of which sliding piece the pin r will have entered, as shown by dotted lines in Fig. 1 of the drawings) coming in contact with the pin 1) as the helical camwheel j revolves, whereby the sliding piece 0 is pushed into a position such that the other end of the groove therein shall meet the helical groove in the wheel 3', into which,as the operation of the machine continues, the pin 1' will then pass, carrying with it the slotted lever 71. The pin 12, as the wheel j continues to rotate, then pushes back the sliding piece 0 into its former position. The card-frame having now been drawn back to its full extent during one revolution of the main shaft 70, it is re turned to its starting-point by the pin a on the lever b traveling through the straight portion of the groove 0 in the cam-wheel f the backward motionof thelever I)' being assisted by means of the spring on the rod h The pattern is moved forward on the rollers A and A to the extent of one line of squares by the projection r on the grooved wheel acoming against and moving the lever u outward from the wheel 0-. This motion operates the pawls" w by means of the rods 0: and y, and the toothed wheels 2 z 2 and rollers A and A are rotated to the required extent. The perforated card is now withdrawn from the card-frame 7c, and a fresh card fixed therein, and the hereinbefore-dcscribed operation is repeated,

' and so on until the whole of the pattern has been read off.

Having thus described my invention and the manner of performing the same, what 1' claim is 1. In a selfaeting reader for the jacquard,
